between the G1 and G2 phases

100 units

A cell biologist carefully measured the quantity of DNA in grasshopper cells growing in cell culture. Cells examined during the G2 phase of the cell cycle contained 200 units of DNA. What would be the amount of DNA at G1 of the cell cycle in one of the grasshopper daughter cells?

growth and development
tissue repair/replacement of damaged cells

The nuclear envelope breaks down.
Chromosomes condense and are attached to spindle fibers.

Which events occur during prophase?
Chromosomes are replicated.
The nuclear envelope breaks down.
Chromosomes condense and are attached to spindle fibers.
The sister chromatids break apart and begin to separate.
b and c only

finishes mitosis by dividing the cytoplasm and organelles of the original parent cell into two separate daughter cells

interphase

telophase

Looking through a light microscope at a dividing cell, you see two separate groups of chromosomes on opposite ends of the cell. New nuclear envelopes are taking shape around each group. The chromosomes then begin to disappear as they unwind. You are witnessing _____.
